Abstract

A psychophysical experiment is performed on two large-size liquid crystal
displays under three viewing conditions to assess perceptual contrast. Based on the
visual data, the performance of CIECAM02 in predicting perceptual contrast under
different viewing conditions is tested and compared with other models by F-test.
Results show that the perceptual contrast models in the form of Weber contrast using
CIECAM02 brightness Q agreed better with the contrast perception of human visual
system compared to the models using luminance, CIELAB lightness L¤, and CIECAM02
lightness J.
